BAGHDAD —  A top Iraqi official said Sunday there was no conclusive evidence that Shiite extremists have been directly supplied with some Iranian arms as alleged by the United States.

Government spokesman Ali al-Dabbagh said Iraq does not want trouble with any country, "especially Iran."

Al-Dabbagh was commenting on talks this week in Tehran between an Iraqi delegation and Iranian authorities aimed at halting suspected Iranian aid to some Shiite militias.

Asked about reports that some rockets made in 2007 or 2008 and seized in raids against militias were directly supplied by Iran, al-Dabbagh replied: "There is no conclusive evidence."
